GOAL OBJECTIVE

LSU 01/18/2005

PROJECT LIFE CYCLE 2

• To Understand project phase

THE PROJECT PHASES

All projects complete roughly the same phases from inception to completion

LSU 01/18/2005 PROJECT LIFE CYCLE 3

OPERATION

DESIGN PDR

DEVELOPMENT CDR

FABRICATION

INTEGRATION

TESTINGFRR

THE DESIGN PHASE

Little to no hardware testing or prototypingDefine science goals and objectivesSystem level design (subject of Lecture 3) System requirements derived from goals and objectives Identify major subsystems and interfaces

Concept hardware and software design Derived from system requirements and constraints Identify parts, costs & availability

Establish tasks, schedule, resource needs and plans for remaining phases of life-cycle

Develop preliminary risk assessment & management plan

Phase terminates with Preliminary Design Review (PDR)

LSU 01/18/2005

PROJECT LIFE CYCLE 4

“Paper” study of all issues to establish major concepts and plans

THE DEVELOPMENT PHASE - 1

Test concepts by prototyping Not building flight hardware Used to gain information necessary to refine or

finalize a design Applies to structure, electronics, sensors and

software

Finalize hardware & software design Complete system design Define interfaces and develop appropriate

Interface Control Documents (ICD) Complete detailed design

LSU 01/18/2005

PROJECT LIFE CYCLE 5

Design

Prototype

Test

Complete Design

Detailed in-depth study when all design components are finalized

THE DEVELOPMENT PHASE - 2

Purchase long lead items (identified at PDR)

Finalize plans for pre-flight phasesFabrication, integration, calibration and testingTasks, schedule, procedures, resource needs, costs

Update risk assessment & management plan

Preliminary plan should already be in use for tracking and mitigating risks during development

Develop preliminary mission operations & data analysis plan

Phase terminate with Critical Design Review (CDR)

THE FABRICATION PHASE

LSU 01/18/2005

PROJECT LIFE CYCLE 7

Training

Integration

Thermal Test

QA / QC Assembly

Order Parts

Inspect/Test

• Parts procurement– Test that parts satisfy flight

requirements before assembly

• Assemble hardware & software subsystems– Training may be required for particular assemblies

– Fabricate component with qualified parts

– If part fails initial inspection and testing, return to assembly for rework / fixing

– If part fails thermal testing return to assembly for rework / fixing

• Once complete move to integration

Implement construction of flight components

THE INTEGRATION PHASE

Make sure all parts fit together, if not then rework

Make sure power system is delivering proper voltage and current

Connect electronics and sensors

Install software and run

Fix issues before proceeding to system testing

LSU 01/18/2005

PROJECT LIFE CYCLE 8

Fit Check

System Testing

Integrate Fix

Test

Subassemblies are put together to make the final package

THE SYSTEM TESTING PHASE

Payload flight certification

LSU 01/18/2005

PROJECT LIFE CYCLE 9

Functional Test

FRR

Fix

Calibration

Thermal Test

Pressure Test

Shock Test

Check Calibration

• Integrated payload must first be fully functional

• Calibration values are determined– Sensors, ADC gain, timing

• Payload must function correctly during thermal, pressure & shock testing– If not, fix and begin again– If OK, then validate calibrations

• Test and test data must be documented

• Proceed to Flight Readiness Review

MISSION OPERATIONS & DATA ANALYSIS (MO&DA)

Mission Operations plan includes the following

Sequence of operations to prepare payload for vehicle integration

Sequence of operations to prepare payload for launch Flight profile requirements Operations, commanding, contingencies during flight Recovery handling and operations

Data Analysis plan describes what happens to the flight data

Flight data handling, processing and analysis sequence Specify data required from vehicle

LSU 01/18/2005

PROJECT LIFE CYCLE 10

Operate payload during flight & obtain science results

PROCESS FLOW DURING LIFE CYCLE

Effort focus changes as a function of phase Design can be highly theoretical involving simulations and

calculations Development involves “experiments” and testing concepts

to gain information necessary for the design Fabrication, Integration, and System testing requires skilled

technical help to realize the design in hardware and software

MO&DA requires “scientists” to direct the proper use of the payload and to turn the data into science results

Resource needs and costs changes as a function of phase

Design requires no hardware and few personnel Development costs increase a bit with some prototyping Major cost in personnel and hardware is in fabrication,

integration and testing MO&DA drops down to no hardware and few personnel

PROJECT RISK MANAGEMENT

“The essence of project management is risk management”

LSU 01/18/2005

PROJECT LIFE CYCLE 12

• Probability of a disaster decreases during the life of a project

• Cost to recover from a problem increases during the project

Catch & correct problems early!

PROJECT MILESTONES

There are three major reviews during the project

Preliminary Design Review (PDR)Follows design phase

Critical Design Review (CDR)Follows development phase

Flight Readiness Review (FRR)Prior to flight

The team must prepare written documents and oral presentations for each review

LSU 01/18/2005

PROJECT LIFE CYCLE 13

PRELIMINARY DESIGN REVIEW (PDR)

The PDR should cover results from your design phase including:

Goals & objectives Preliminary System design Concept hardware & software design Tasks, schedule, resource needs, long-lead items Preliminary risk assessment & management plan

Should show that you have “thought the problem through”

Include written document and oral presentation Format of document will be discussed in Lecture 8

A member of the LA ACES Project will attend and participate in the PDR

LSU 01/18/2005

PROJECT LIFE CYCLE 14

CRITICAL DESIGN REVIEW (CDR)

The CDR should cover results from your development phase including:

Resolving issues identified during the PDR Prototyping results and “proven” designs Completed system design and defined interfaces Finalize tasks, schedule, procedures and costs Updated risk assessment & management plan Preliminary MO & DA plan

Determines whether you are ready to begin building your payload

Include written report and oral presentation

Precise date for CDR should be identified during PDR

LSU 01/18/2005

PROJECT LIFE CYCLE 15

FLIGHT READINESS REVIEW (FRR)

The FRR reviews all aspects of your payload Documentation of as-built configuration Is payload safe? Will payload perform properly? Does payload satisfy the flight constraints?

The FRR will determine whether you are allowed to attach your payload to the flight vehicle!

Written FRR document sent to LA ACES Project 2 weeks before flight

Oral FRR presentation during the launch tripDetails about what is expected during the

FRR are provided in Ballooning Unit, Lecture 5
